基于WebSocket的Web实时通信系统

摘要

The military field generally uses the C/S architecture for communication,but it has the high cost of system deployment and the difficulties of upgrade. However,the B/S architecture does not have the problems. In order to solve the problem of high-bandwidth in B/S architecture,firstly,the existing WEB-server-push technologies are analyzed and summarized,and then the paper realizes the WEB-server-push technology based on WebSocket. The experimental results prove that this method is high efficiency and small bandwidth. Finally,a real-time communication system which is based on Web is introduced.%传统军事信息系统一般采用C/S架构，但是其系统部署成本高，软件升级维护困难。而采用B/S架构则不会存在此问题，但是B/S架构通信量大、网络带宽占用高，不利于在战场环境中进行服务器推送。针对此问题，首先对目前存在的WEB服务器推送技术进行了分析和总结；接着实现了基于WebSocket的服务器推送技术，并通过实验证明了该方法网络带宽占用小，效率高；最后详细介绍了如何实现一个WEB实时通信系统。
